ASF SeaTest NO2- Nitrite Fish Aquarium Water Test Kit

Get an accurate read of the NO2 level of your aquarium with the ASF SEATEST NO2- (Nitrite) Fish Aquarium Water Test Kit. In high concentrations, NO2 can produce a toxic environment for fish and other animal life. Uneaten food, waste, and other factors can contribute to the development of ammonia and nitrite, followed by a further breakdown into nitrate. In low concentrations, this is not dangerous but the nitrite value of your aquarium or pond should not exceed 0.3 mg/L. Monitoring is key in all stages of aquarium and pond life, but it is especially important in the set-up phase, when filter bacteria have not been developed. This is also great for use with aquatic turtles and aquatic amphibians.
